Why Mulching Matters

Mulch offers a wide range of benefits:

  • Moisture Retention – Reduces water evaporation, meaning less frequent watering.

  • Weed Suppression – Blocks sunlight, preventing weeds from sprouting.

  • Soil Temperature Regulation – Keeps soil cooler in summer and warmer in winter.

  • Improved Soil Health – Organic mulch breaks down and enriches the soil.

  • Aesthetic Appeal – Gives your garden a neat, finished look.

Choosing the Right Mulch

Different gardens benefit from different mulches. Here's a quick overview:

1. Organic Mulch (Bark, Wood Chips, Straw, Leaves)

  • Breaks down over time to improve soil

  • Ideal for garden beds, vegetable patches, and under trees

  • Needs occasional replenishment

2. Inorganic Mulch (Pebbles, Stones, Rubber)

  • Long-lasting and low-maintenance

  • Great for modern designs or high-traffic areas

  • Doesn’t enrich soil but prevents weed growth

3. Coloured or Dyed Mulch

  • Available in red, black, and brown to match your design

  • Use with caution in garden beds — make sure it’s non-toxic and suitable for plants

How to Apply Mulch Properly

  1. Clear the Area – Remove weeds and loosen the soil.

  2. Set the Depth – Apply 5–7 cm of mulch (too thin = weeds, too thick = suffocates roots).

  3. Keep Clear of Stems – Leave space around plant bases to prevent rot.

  4. Top Up Seasonally – Reapply when mulch decomposes or fades.

Final Thoughts

Mulching is one of the easiest ways to boost the health and beauty of your garden — especially in Melbourne’s hot, dry summers. It conserves water, suppresses weeds, and enhances soil quality, all while giving your landscape a clean, professional finish.
